from IMDB
While not initially a box-office success with audiences,[28] Under the Silver Lake has garnered a cult following who are convinced that there are hidden meta-clues, codes and ciphers sprinkled throughout the film waiting to be discovered. These include references to the mystery surrounding the identity of the dog killer, various different cyphers or codes, geocoding systems, and even analysis of fireworks in the film, connecting the sound pattern they emit to Morse code. In certain scenes in the film there is graffiti that can be seen in the toilets and on a wall and which are coded with the Copiale cipher.
